Fill Materials

Nylon-Type 6
Good bend recovery, abrasion resistance, flex fatigue resistance, and chemical resistance.

Nylon-Type 6.6
Similar properties as 6.0 nylon, but better bend recovery and wet stiffness. High heat deflection temperature.

Nylon Type 6.12
Highest quality nylon with excellent bend recovery. Used in applications that require a low water absorption.

Nylon-Conductive
Offers superior performance in static control or conductive brushes. The conductivity is unaffected by humidity. Suitable for uses up to 230ºF.

Polypropylene
Versatile filament for a variety of applications. Excellent wet stiffness. Good bend recovery, but will take a set more easily than other material.

Polyester
An economical substitute for nylon Type 6.6 and 6.12. Ideal for wet applications since its water absorption is very low. Also excellent bend recovery and solvent resistance.

Abrasive Nylon
Nylon monofilament impregnated with either silicone carbide or aluminum oxide. Long wearing material available in several filament diameters and grit sizes.

Horse Hair
Black or grey in color. Very good durability. Soft to slightly stiff texture gives scratchless cleaning for highly polished surfaces.

Goat Hair
Very fine hair often used for very short trim soft brushes.

Steel
High carbon wire with excellent fatigue resistance.

Stainless Steel-Type 304
Highly resistant to corrosion and higher temperatures. Often effective in contamination areas and after-rust areas.

Stainless Steel-Type 316
Superior for high corrosion resistance and more effective in highly contaminated applications.

Brass
Non-ferrous and softer wire compared to steel or stainless steel. Effective for reducing heavy static in a concentrated area.

Phosphorous Bronze
Non-ferrous wire. Better temper than brass with non-corrosive properties.

Tampico
Derived from the Agave plant grown in Mexico. Natural creamy white color. Unsurpassed in applications requiring liquid retention, scrubbing, and surface finishing.

Bassine
Dark brown bassine is a coarse dyed fiber from palm trees grown in India. Bassine is an excellent material for heavy-duty scrub brushes.
